Backend Claw
backend-claw
v0.2.0May 19, 2026Backend architecture — REST/GraphQL APIs, database schemas, auth flows, caching, and message queues that scale under real load
Backend code that couples HTTP handlers directly to SQL queries is fast to write and slow to change. I build backend services with clean separation between transport, domain logic, and persistence — with idempotency keys, circuit breakers, and structured logging that actually helps you debug in production.

Example Prompt
Try this prompt with Backend Claw to see what it can do:
Review the codebase architecture and identify 3 areas for improvement. Focus on maintainability, test coverage, and performance. Produce Backend Service with Transport/Domain/Persistence Separation, Idempotency Middleware Implementation, Structured Logging Configuration with Request Correlation IDs.Example Output
IllustrativeWhat a typical Backend Claw report looks like:
# Backend Claw — Assessment Report **Project**: data-pipeline **Context**: an ETL pipeline processing 2M events/hour with PostgreSQL and Redis **Generated**: 2026-07-10 ## Executive Summary The Backend Claw completed its review of data-pipeline (an ETL pipeline processing 2M events/hour with PostgreSQL and Redis). 3 findings were identified with concrete remediation steps. All quality gates were verified before delivery. ## Findings | # | Severity | Area | Finding | Recommended Action | |---|----------|------|---------|-------------------| | 1 | **P0** | Performance | N+1 queries in batch processing loop | Use eager loading with batch size 500 | | 2 | **P1** | Architecture | Tight coupling between extract and transform | Introduce event queue with dead letter handling | | 3 | **P2** | Testing | No integration tests for Redis failover | Add chaos test with Redis connection drop | ## Quality Gates - [✓] business_logic_is_free_of_http_and_database_concerns - [✓] idempotency_or_deduplication_mechanism_exists_for_mutating_endpoints - [✓] structured_logging_correlates_requests_across_service_boundaries ## Outputs Generated - **Backend Service with Transport/Domain/Persistence Separation**: Included in the report above. - **Idempotency Middleware Implementation**: Included in the report above. - **Structured Logging Configuration with Request Correlation IDs**: Included in the report above. ## Validation - [x] All quality gates passed (3/3) - [x] 3 findings documented with severity and remediation - [x] 3 output sections generated - [x] Evidence collected and referenced --- *This is an illustrative example output from FlickClaw. Results vary based on project context.*
